Unprotect ThinkTank Version 1.000 (There are TWO versions)
1. Diskcopy the original disk to another floppy or copy the
files to a hard disk.
(If you have version 1.001 go to 1.001 instructions)
2. Rename TANK.EXE, type RENAME TANK.EXE TANK.XXX
3. Rename INSTALL.EXE, type RENAME INSTALL.EXE INSTALL.XXX
4. Type DEBUG TANK.XXX and press ENTER
5. At the - prompt, type R . Look for the value in the DS register
(left-hand column of the second line of the R display).
6. Add 2000 to that DS value. i.e. if the R display showed DS=0D5F
then you will use 2D5F. I will refer to this value later as xxxx.
7. Check that your version is the same. Type the following:
U A8E9 and press ENTER
You should see JZ A8EE on the first line of the display. If so, this
patch should work.
8. Type E xxxx:59 90 90 Enter
9. Type E xxxx:5C B8 00 00 90 Enter
10. Type E A8E9 EB 03 Enter
11. Type E A902 EB 03 Enter
12. To save these changes, now type W
13. Type Q to exit DEBUG.
14. Rename TANK back to it's original name RENAME TANK.XXX TANK.EXE
15. At DOS, type DEBUG INSTALL.XXX
16. Check the version to make sure this will work. Type
U 2D01 and press Enter. You should see JZ 2D06 on the first line.
17. If ok, then type E 2D01 EB 03 Enter
18. Type E 2D1A EB 03 Enter
19. Type E 50D9 90 90 Enter
20. Type E 50DC B8 00 00 90 Enter
21. To save the changes, type W
22. To quit DEBUG, type Q
23. Rename INSTALL back to original name RENAME INSTALL.XXX INSTALL.EXE
That's it. The original floppy is no longer needed. you may copy the
TANK files to a hard disk, network or other floppy with normal DOS
commands.
